Description
Изобретение относитс к способам взрывани зар дов в нефт ных скважинах путем инициировани взрыва с помощью детонирующего шнура.The invention relates to methods for blasting charges in oil wells by initiating an explosion using a detonating cord.
Описываемый способ отличаетс от известных тем, что шнур обвивают вокруг боковой поверхности зар да в один и более оборотов.The described method differs from the known ones in that the cord is twisted around the side surface of the charge at one or more turns.
Применение такого способа позвол ет упростить и удешевить конструкцию перфораторов, рассчитанных на работу в глубоких скважинах .The use of such a method makes it possible to simplify and cheapen the design of perforators designed for operation in deep wells.
На чертеже изображен зар д, примен емый при взрывании, к продольном разрезе.The drawing shows the charge applied during blasting to a longitudinal section.
Зар д 1 помещаетс в оболочку 2 из стали, стекла, пластмассы, дюралюмини или другого материала, образующего при взрыве зар да большое количество мелких осколков. На боковую поверхность оболочки в один или несколько оборотов наматываетс детонирующий щнур 5. При взрыве к центру зар да распростран етс сильна сход ща с ударна волна, создающа резкий скачок давлени и плотности.Charcoal 1 is placed in a shell 2 of steel, glass, plastic, duralumin, or other material that, in the course of an explosion, charges a large number of small fragments. A detonating cord 5 is wound on the side surface of the shell in one or several turns. In an explosion, a strong converging shock wave propagates to the center of the charge, creating a sharp jump in pressure and density.
При использовании -предлагаемого способа взрывани представл етс возможным инициировать взрыв зар дов через достаточно толстые стенки герметизирующей оболочки 2, примен емые при перфорации и торпедировании глубоких и сверхглубоких скважин. Благодар большому импульсу, передаваемому от шнура 3, отпадает необходимость в дополнительном детонаторе.With the use of the proposed proposed blasting method, it is possible to initiate a charge explosion through the rather thick walls of the sealing shell 2 used in the perforation and torpedoing of deep and ultra-deep wells. Due to the large impulse transmitted from cord 3, there is no need for an additional detonator.
